QLab Pro 4.6.8 macOS | 15.2 MB


QLab makes it simple to create rich multimedia designs for live performances and installations. From Broadway to the West End, in churches, museums, store fronts, concert halls, and theaters around the world, people use QLab to bring their audio and video to life.

Simply powerful show control
QLab allows you to design and operate amazing multimedia performances from your Mac OS X computer. A single QLab workspace can control audio, video, MIDI, OSC, and more.

Amazingly deep, surprisingly easy
Using building blocks called “cues”, you can create sophisticated designs in seconds.

Getting started is as simple as dragging in a file and pressing “GO”. From there, add commands to fade volume, animate videos, or add audio and video effects.
Once you master the basics, become a power user with advanced features like scripting, video corner pinning, multi-projector edge blending, audio localization, or even building multi-computer designs by sending commands to other QLab machines on your local network.

The industry standard.
Battle-tested and used by designers around the world, QLab is the tool of choice in venues large and small.

Audio Effects
You can now apply live audio effects to all your cues: EQ, pitch shift, reverb, and more. Add audio effects to individual cues, across all cue outputs, or on your device outputs.

Dynamic Effects
The powerful new Fade Cue can adjust your audio effect parameters in real time. It can even adjust playback rate, to dynamically speed up or slow down your audio, with or without pitch shifting.

Live Audio Inputs
The new Mic Cue offers up to 24 channels of live audio inputs. Plus all those routing, fading, and audio effects you get on Audio Cues? You get those on Mic Cues too.

What’s New:

Version 4.6.8:
A bug in the short-lived version 4.6.7 which caused windows to draw as blank white squares under some circumstances.

  • The OSC message which allowed you to set a Video, Camera, or Text cue’s video effect have been changed from /cue/{cue number}/effect {effect number}, which did not work (for boring technical reasons) to /cue/{cue number}/effectIndex {effect number} which does work (also for boring technical reasons.)


  • Changing the background color of a Text cue using AppleScript now works using the “backgroundRgbaColor” property of the cue’s “text format” record.
  • A rare race condition that could cause QLab to freeze when closing audio devices.
  • A rare and bizarre bug where using Apple’s AUMatrixReverb broke a certain kind of random number generator which could in turn break how QLab identified video surfaces.
  • Performance improvements with opening workspaces.

Compatibility: OS X 10.10 or later, 64-bit processor
